Fasten the startup time of simulation?

Rune
I am trying to simulate a rather large circuit with extracted parasitics. I am running IC5.1.41 with MMSIM11. From when I push "Netlist and run" the time to start the simulation can take hours, while the simulation (i.e. from when spectre is instantiated) itself is like 30 minutes. Is there a way to make this initiation become faster?

  • This is quite likely a bug that's been fixed in IC61X, but if it's what I think it is, please open the extracted view in a window prior to opening ADE. The issue was that at various points ADE was opening and closing the extracted view (when processing the outputs, and during netlisting) - and because the extracted view was not open elsewhere it was flushing it from memory and re-reading from disk each time. Opening in a window prevents it from flushing from memory.

    Regards,

    Andrew.
